Blockchain ID Layer Launches Mobile Idenity App

Blockchain-based identity layer Billions Network announced the launch of its identity mobile application for both Android and iOS devices.

According to a Thursday statement shared with Cointelegraph, Billions Network’s identity system is AI-proof. The announcement follows Polish investor Borys Musielak’s April demonstration of how ChatGPT can generate photos of government-issued IDs likely to pass photo-based Know Your Customer (KYC) checks.

“As AI continues to erode trust in traditional verification methods and digital interactions, this launch ensures people can safely and privately enjoy personalized digital experiences,” Evin McMullen, co-founder and CEO of Billions, said.

Billions’ implementation does not rely on proprietary hardware or invasive biometric data, with the exception of liveliness checks to complete verification. Instead, the new mobile app leverages near-field communication (NFC) chips in modern passports and ID cards, as well as liveliness checks and cryptographic proofs.

An established ecosystem

The system leverages institutional KYC and the Privado ID infrastructure stack, and was created by the core contributors behind the open-source zero-knowledge proof (ZK-proof) framework Circom. Over 9,000 Web2 and Web3 services — including TikTok, Aptos and World — leverage Circom’s ZK-proof-based authentication.

Billions Network claims that its implementation stores no personal data and requires no proprietary hardware. The initial rollout includes support for verification via liveliness checks and NFC chip verification of documents.

In the future, Billions plans to integrate a web wallet interface and a verifiable KYC service for institutional platforms. Another future product is the DeepTrust framework, which would enable artificial intelligence to establish an onchain identity that also facilitates its association with the controlling entity.

Where is the data stored?

In a joint statement, Privado ID CEO David Z and chief technology officer Oleksandr Brezhniev explained that data is stored both locally and on end-to-end encrypted cloud storage. When using the mobile application, user data is stored locally on the device and personal information is not shared with third parties unless the user explicitly decides to share some details.

To enable multi-device support and web-based service, Billions also stores end-to-end encrypted data in the cloud. Still, identity data remains offchain and is encrypted with the user’s private keys to prevent leakage.
